What is a P4 indoor LED display?
A P4 indoor LED display is a full-color LED screen with a pixel pitch of 4 millimeters, so each square meter holds about 62,500 dots. Unlike LCD video walls, there are no bezels between panels. The screen is one continuous image. It works well in rooms where the closest viewer sits at least 4 meters away. Common uses include lecture halls, exhibition centers, airport terminals, and hotel function rooms. Because the pixel pitch is larger, the screen costs less than P2 or P2.5 models and runs cooler with lower power draw.

What Makes Our P4 Indoor LED Displays Different
The 3840Hz refresh rate helps prevent flickering when you take photos or stream live video. The high grayscale keeps colors looking natural even when the screen brightness is turned down. From 4 to 10 meters away, the image stays clear, and the text remains easy to read.
This P4 LED wall works with NovaStar, Colorlight, and Linsn control systems. You do not need to change your existing system or worry about compatibility issues when adding new modules later.
The modular P4 LED wall uses seamless splicing with no visible gaps between modules. The entire screen is one continuous image, so the content looks complete without black lines or breaks.
Adjustable brightness works in different indoor light conditions. 140° horizontal and 120° vertical viewing angles keep side views clear without major color shift.
The P4 LED screen consumes less power than smaller-pitch displays. It uses a fanless design, so there is no noise when running. This makes it suitable for conference rooms, classrooms, and control centers where quiet is needed.
The control system is pre-configured at the factory. When you receive the screen, you can plug it in and use it without a complex setup. If you need to make changes later, the software interface is straightforward, and we can provide remote guidance
How to Change Content on a P4 Indoor LED Display
You can update the content on a P4 indoor LED display using a USB drive, a computer, or a mobile app. Connect the screen to WiFi or a network cable, then open the control software on your computer to upload images, videos, or text. For smaller standalone screens, you can also plug a USB drive directly into the receiving card. We pre-configure the control system before shipping, so you can start uploading your content right after you receive the screen.
Consistent Quality P4 Indoor LED Displays
At SWX, P4 LED screen control quality is in three stages. First, LED chips go through brightness and color sorting before assembly. Second, each module is calibrated after assembly to keep the whole screen uniform. Third, every batch runs a 72-hour aging test before shipping to catch early failures. This helps ensure that modules from different batches remain consistent when you need spare parts later.

What Our Customers Say About SWX P4 Indoor LED Displays

Australia – Shopping Mall Operations ManagerWe installed a P4 indoor LED screen at the store entrance to play promotional videos. The colors look natural, and people passing by stop to watch. The packaging was very sturdy, and there was no damage during sea freight.
UAE – Retail Store Owner
The P4 indoor LED modules are magnetic. Use a suction tool to pull the damaged module off the front. Then press the new module onto the cabinet until it clicks into place. The whole process takes a few minutes. You do not need to access the back of the screen or use any special tools.
For a 15 square meter conference room, the viewing distance from the screen to the furthest seat is usually around 3 to 4 meters. P3 is more suitable in this case because its pixel pitch is smaller, so text and charts will look sharper. P4 LED video wall works better for larger rooms where people sit 4 to 10 meters away. For a room of this size, we recommend P3 over P4.
For a basic P4 LED video wall setup with standard brightness (800 to 1000 nits), 1920Hz refresh rate, and a standard control system, the price is usually between 280 and 400 dollars per square meter. If you go for higher specs, like a 3840Hz refresh rate, NovaStar control system, and branded LED chips, the price will be higher. The final cost depends on what you need. Tell us your project requirements, and we can send you a detailed quote.
The back of each cabinet in the P4 indoor LED video wall is made of aluminum, which helps release heat. There are also ventilation holes on the cabinet to let hot air escape. No fans are used, so the screen runs quietly.
The P4 LED display’s power consumption is about 200 to 300 watts per square meter. If the screen shows a full white image, it can go up to 600 to 800 watts. But during normal use, like playing videos or images, the actual power draw is closer to the average.
To install a P4 indoor LED display, you can take a look at the CAD drawings we provide. They show where to build the steel frame and how to hang the cabinets. The cabinets have quick-lock connectors, so one person can attach them without special tools. Once the cabinets are in place, just press the modules onto the magnetic pads. If you need help during installation, our engineers can guide you through a video call.
The choice mainly depends on your viewing distance and budget. The closer your audience sits to the screen, the smaller the pixel pitch you should pick. You can refer to the table below:
| Model | Pixel Pitch | Best Viewing Distance | Suitable For | Cost Level |
|---|---|---|---|---|
| P2 | 2mm | 2–5 meters | High-end conference rooms, studios, and control rooms | Higher |
| P2.5 | 2.5mm | 2.5–6 meters | Conference rooms, retail stores, and shopping malls | Medium-High |
| P3 | 3mm | 3–8 meters | Conference rooms, exhibition halls, retail stores, display spaces | Medium |
| P4 | 4mm | 4–10 meters | Large auditoriums, hotel lobbies, and long-distance viewing | Lower |
